    arm64: dts: imx8mm-venice-gw71xx: fix USB OTG VBUS · bd306fdb
    Tim Harvey authored
    The GW71xx has a USB Type-C connector with USB 2.0 signaling. GPIO1_12
    is the power-enable to the TPS25821 Source controller and power switch
    responsible for monitoring the CC pins and enabling VBUS. Therefore
    GPIO1_12 must always be enabled and the vbus output enable from the
    IMX8MM can be ignored.
    
    To fix USB OTG VBUS enable a pull-up on GPIO1_12 to always power the
    TPS25821 and change the regulator output to GPIO1_10 which is
    unconnected.
